April 7, 1971 1 l <br />MEMO TO: Members of the Common Council <br />SUBJECT: Ordinance approving a contract to construct a sewage lift station <br />on North Michigan Street. <br />The Sewage Lift Station located on Michigan Street in front of the Northside <br />Water Pumping station was installed about 1954. Over the years, the station <br />has deteriorated to the point where the station is virtually.out of service. <br />In addition, the sewage load on the station has increased. To further complicate <br />the maintenance situation, the station is located in the northbound lane of U.S. 31 <br />This makes service hazardous to Wastewater personnel and generally inconvenient <br />to motorists using the highway when the station is serviced. <br />At the request of Wastewater personnel, the situation pertaining to this lift <br />station was investigated. Engineering plans were subsequently developed and bids <br />taken for this station. Generally the characteristics of the new station are: <br />1. Increased capacity to handle even reasonable storm flows without <br />discharging sewage to the river. <br />2. The new station will be located in the front yard of the Northside <br />Pumping Station so that maintenance may be performed safely and with a minimum <br />of inconvenience to the public. <br />3. The new station will utilize pumps instead of pneumatic ejectors. <br />The reliability of the new system is believed to be very high. <br />Since the present situation in which raw sewage is being bypassed almost <br />continuously to the river is unreasonable, we recommend that the ordinance <br />confirming the contract to replace this pumping station be adopted. <br />David A.
